| abstract |
The invention relates to cephalosporins represented by the formula (I), where m is equal to 1 or to 2, n is equal to zero, to 1 or to 2, A and B represent organic residues, and R1 and R2 represent organic groups or halogen or hydrogen atoms, these cephalosporins having an elastase inhibiting power. Two processes allowing the preparation of these compounds starting from the corresponding 4-acyl cephem are also described. |
